General Description
The DG417L/DG418L/DG419L precision, CMOS ana-
log switches feature low on-resistance (RON = 35
),
guaranteed RON matching between switches (3
max), and guaranteed RON flatness over the signal
range (4
max). These switches are +3V logic-com-
patible when powered from ±15V or ±12V supplies.
The switches conduct equally well in either direction,
and feature low charge injection and low power con-
sumption. The DG417L/DG418L/DG419L also offer low
off-leakage current over temperature (less than 5nA at
+85°C).
The DG417L/DG418L are single-pole/single-throw
(SPST) switches. The DG417L is normally closed, and
the DG418L is normally open. The DG419L is single-
pole/double-throw (SPDT) with one normally closed
switch and one normally open switch. Switching times
are less than 175ns for tON and less than 185ns for
tOFF. These devices operate with a single +9V to +36V
or bipolar ±4.5V to ±20V supplies.
The digital input has a +0.8V logic-low threshold and a
+2.0V logic-high threshold, ensuring +3V TTL and
CMOS-logic compatibility. The DG417L/DG418L/
DG419L are available in a tiny 8-pin MAX, 8-pin SO,
or convenient 8-pin plastic DIP. All products are rated
at the extended temperature range of -40°C to +85°C.
